Abstract

Reconnaissance work carried out in north-east Southern Rhodesia has shown that the Umkondo system, previously known in the Mozambique belt, extends into the Zambesi belt. It is further demonstrated that the two belts were broadly continuous in structure and metamorphism during the important orogeny c. 500 m.y. The possibility that the mobile belts were active considerably earlier than 500 m.y. is discussed.
